[ _ ] Generate site usage layout for temporary facilities, assembly areas, and material deliveries for all phases of construction.
[ _ ] Identify potential and critical space and time conflicts.(Dawood et al, 2005).
[ _ ] Update site organization and space usage as construction progresses.
[ _ ] Represent construction schedule in relation to spatial features both temporary and permanent. (Chau et al, 2005).
[ _ ] Select a feasible construction scheme. (Dawood et al, 2005).
Description:
A process in which a 4D Model is used to gra[graphically represent both permanent and temporary facilities on site, with the construction activity schedule. Additional information incorporated into the model can include labor resources, materials and associated deliveries, and equipment location. Because the 3D model components are directly linked to the schedule, site management functions such as visualized planning, short term re-planning, and resource analysis can be analyzed over different spatial and temporal data (Chau et al, 2005).
Potential Benefits:
Maximize available area for construction site.
Minimize both vehicular and pedestrian traffic disruption.
Maximize accessibility to site and adjacent properties. (Chau et al, 2004).
Increase coordination and communication on site between disciplines and their construction execution plans.
Effectively plan site activities.
Visualize the progress of the construction project at different stages.(Heesom et al, 2004)
Develop and evaluate alternative construction plans.
Identify problems with site logistics and layout before construction.
Decrease costs in construction waste. (Dawood et al, 2005).
Levels of Detail Considerations:
Level of detail of model equals the level of detail of construction schedule.
3D model of both permanent and temporary facilities on site for all phases of construction. (Heesom et al, 2004).
Information included in model and database needs to be accurate and must be the right level to make informed decisions.
Team Competencies Required:
Ability to read drawings
Ability to think in 3D
3D Model Manipulation
Knowledge in scheduling applications
Knowledge of construction means and methods
Characteristics in order to substantiate BIM use:
Project - Congested site, constant deliveries, complex geometry and systems, high perceived risk
Organization - Access to appropriate hardware and software for model development, training, and IT Department
Environment - Critical access points
Contract - Modeling process is adjusted for delivery method.
Process - Time-critical project
Potential Modeling Methods:
Planning model from Architect.
Integrate construction schedule from contractor.
Construction Model with integrated schedule through second application. (Chau et al, 2004).
Potential Outputs:
Additional annotations added to model to explain construction scheme and planning information and assist in decision-making (Heesom et al, 2005).
Excavation modeling
Safety planning tool
Legal / Commitment Considerations:
The authoring team currently develops and owns the model, but shares between the other disciplines.
Additional Resources:
General Description:
Site utilization is the site usage layout for temporary facilities, assembly areas, and material deliveries for all phases of construction. (Dawood, 2005).
Quantitative Studies:
There are no quantitative studies at this time.
Case Study Examples:
San Mateo County Health Center (4D simulations between AutoCAD and Primavera). (Chau et al, 2004).
Walt Disney Concert Hall (4D prototype tool for analysis of subcontractor coordination, design constructibility studies, and the verificiation of the construction execution plan). (Heesom et al, 2004).
Lynchburg General Hospital (4D visualization of the construction sequencing and progress). (Heesom et al, 2004).
Gallicon Project : Salford University, UK (4D simulation of different construction phases). (Heesom et al, 2004).
Logan International Airport moderinzation project (4D simulation planning). (Heesom et al, 2004)
Software Applications:
3D Modeling Software: Revit, Bentley Products, Vicon Constructor
VIRCON: database program which incorporates AutoCAD and MS Project with the VIRCON planning, analysis, and visualization tools. (Dawood et al, 2005).
